Well 2 of those implementations were Mutiny Wallet run so the proposal has died with them it seems. They were the only wallet provider that supported it. Alby used to say they would implement it (and presumably would if it had been merged). Now it feels fully abandoned.

We have just moved on with using the flawed onboarding flow and as such virtually no services interact with NWC at all.

I don’t think it can be merged as is anymore unfortunately. I think Alby is working on some other flow now 🤷‍♂️
